I attached A pic I took with my phone of my 08 535xi with the 1st custom set ever made of Donz Forged wheel style Masseria in HIGH CONCAVE.
I would like to THANK my boy Weiz the owner of EAA that makes wheels in CA for Donz, Rennen, Savini, D2 Forged, and more high end companies.
Rennen has an X CONCAVE line that I took the idea from. I would like to thank Joe @ his shop in NYC for helping me make this happen, and making sure the offsets,
and widths were correct with no rub, and Rich for the BMW caps. I have the car lowered with H&R springs with stock struts. with stock 17's the ride was horrible in NYC,
but with the 20's the ride, improved and a lot I don't know if its the width of the rims which are 9'' all around, or type of tires which are Falken FK-452's. The center is brushed
aluminum with 4''chrome lips all around (I don't think any XI has 4'' lips front & back) with ET35 offset. The car sits perfect with H&R springs (not too Low, or High). I will take
A photo shoot this weekend, and post more pics. If anyone wants to take any Rennen, or Donz Forged wheel, and make it into a Concave, Ultra Concave, X Concave, 1 Piece
Monoblock (Their Lightest Wheel) or Monoblock Concave, let me know it can be done. This year at SEMA they will propose the Rennen & Donz 1 PC Cast X Concave Line.

 

lookin sweet, another Xi owner ftw : )

 

We've gotta get some pics of these, brother

These look very reminiscent of the rims AngleSlayer has on his M5 (generally regarded as one of the 2-3 most beautiful E60s currently on the forum)

Thanks again for the info in the PM and all the help!
